Hardware information Introduction
(20 kHz measurements are missing the correct bandpass filter and therefore show a larger THD that is coming from the generator)
Dynamic parameters are measured at ±1 V input range (if no other range is stated) and 50

termination with the samplerate specified in the table. Measured parameters are averaged
20 times to get typical values. Test signal is a pure sine wave generated by a signal generator and a matching bandpass filter. Amplitude is >99% of FSR. SNR and RMS noise parameters
may differ depending on the quality of the used PC. SNR = Signal to Noise Ratio, THD = Total Harmonic Distortion, SFDR = Spurious Free Dynamic Range, SINAD = Signal Noise and Dis -
tortion, ENOB = Effective Number of Bits.
